The log line you've shared is from the MySQL source connector's initial sync process. It shows the connector emitting a primary key (PK) load state checkpoint for the stream

metrics_ERROR_INFO

. Here's what each field in the state means: •

stateType=primary_key

– The stream is currently in the initial primary key load phase (not yet in cursor-based incremental sync). •

pkName=ERROR_INFO_ID

– The primary key field being used to paginate through the table. •

pkVal=116280023

– The last primary key value processed so far. The next sync chunk will resume from records with a PK greater than this value. •

incrementalState={}

– The incremental (cursor-based) state is currently empty, which is expected during the initial PK load phase. This behavior is by design. During the initial load, the connector reads the table in chunks ordered by the primary key, emitting state messages at each checkpoint so that a failed sync can resume from where it left off rather than starting over. [SingleStoreInitialLoadStreamStateManager] Once the initial PK load completes, a final state message is emitted with the incremental (cursor-based) state, and subsequent syncs will use cursor-based logic instead. [SingleStoreInitialReadUtil] In short, this log line is normal and expected behavior — it indicates the connector is making progress through the initial full table load for

metrics_ERROR_INFO

and has processed records up to

ERROR_INFO_ID = 116280023

. No action is required unless the sync is failing or stalling. If you are seeing errors alongside this log, please share those for further diagnosis. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
